CVE-2026-22697 - CryptoLib Plugin
CVE-2026-22697
CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, CryptoLib’s KMC crypto service integration is vulnerable to a heap buffer overflow when decoding Base64-encoded ciphertext/cleartext fields returned by the KMC service. The decode destination buffer is sized using an expected output length (len_data_out), but the Base64 decoder writes output based on the actual Base64 input length and does not enforce any destination size limit. An oversized Base64 string in the KMC JSON response can cause out-of-bounds writes on the heap, resulting in process crash and potentially code execution under certain conditions. This issue has been patched in version 1.4.3.

Potential Impact
Severity is HIGH (CVSS 7.5). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.
Exploitability Assessment
Exploitability is assessed as High based on published exploit references, remote code execution potential.
Primary risk drivers: published exploit references, remote code execution potential
Mitigation Recommendations
Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.
Detection & Monitoring
Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.
Business Impact Lens
Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
